Fault-tolerant Design of Computer Cyclic Check and Control System

Computer cyclic check is widely used in many different fields. Some limitations as well as bugs of classical algorithms in the computer cyclic check system are analyzed in detailed. In order to overcome these advantages, two series of new algorithms are set up in this paper, one of which is built for the computer cyclic check system with fixed reference value and the other for the computer cyclic check under operation steering with variant directive trajectory. Theoretical analysis and simulation result shows that these new algorithms are fault-tolerant and safe. These new algorithms can be widely used in engineering to improve safety of computer cyclic check system.
